Cummins is named after the inventor Clessie Lyle Cummins, who played a key role in the founding of the company. He was from 1919 supported financially by William Irwin, as he began to improve the design of existing diesel engines.

Duesenberg Cummins and experimental car

To highlight the advantages of the diesel engine Cummins built 1929-1934 for the 500 miles of Indianapolis some Duesenberg race car. Dave Evans (1898-1974) went on the 13 final ranking with his Duesenberg Cummins 1931; was remarkable that he had covered the entire distance without a pit stop. In the same year a Duesenberg Cummins presented in Daytona Beach the world record for diesel vehicles at 100.75 mph ( 162.141 km / h ) a. 1934 " Stubby " Stubblefield qualified in a Duesenberg race car just with the second worst time for Indianapolis. His car had a six cylinder diesel two-stroke engine from Cummins. It held the whole 500 miles and finally finished 12th Final Rank. Cummins diesel were occasionally fitted to 1952 Indy race car ..

1930 Clessie Cummins was driven with a converted to Cummins Diesel car from Indianapolis to New York. The distance is 792 miles ( 1274 km ), he spent fuel for just U.S. $ 1.38. In 1935 he exhibited at the Motor Show of New York from a Auburn- passenger car with Cummins diesel engine. The car did not go to series.

Recent History

Between 1963 and 1968, Cummins had a major customer in Germany: Krupp was to drive his truck in the early 1960s in search of a replacement of its traditional, but hardly competitive two-stroke diesel engines and found this at Cummins. From 1963 until the cessation of truck production at Krupp 1968 Cummins engines were used.

In 1980, Cummins along with the Case Corporation, a joint - venture called Consolidated Diesel Corporation, which was to develop and manufacture diesel engines. 2008 saw the purchase of Case New Holland 's 50 % interest in this joint venture.

1996, it was founded with Iveco and New Holland joint venture European Engine Alliance (EEA ) on which each of the companies was involved with 1/3. Cummins sold his share of the joint venture in 2008 to Fiat Powertrain Technologies.

Cummins is working on a 4.2-liter V6 and a 5.6-liter V8 to be installed in Dodge Ram pickups of the 2010s series. This new engine family uses an aluminum cylinder head with four valves, turbocharger and piezo-electric injection. The V6 is specified at 190 hp (142 kW) and 617 Nm.

The built- in Dodge Ram 5.9 l (B- series) has proven to be very successful and the myth that diesel engines are unpopular among Americans refuted. Heavy-duty diesel engines with more than 15 liters capacity are manufactured in Seymour (Indiana, USA), Daventry (England) and Pune ( India).
